Even without any external clues, your body can predict events that are about to happen. For example, you might sense that your boss is about to show up while you're playing a video game at your desk. That's the conclusion of Northwestern University researchers who analyzed the results of 26 studies published between 1978 and 2010, and published their findings recently in the journal Frontiers in Perception Science. It has already been shown that your subconscious mind sometimes knows more than your conscious mind, according to study author Julia Mossbridge, a research associate in the visual perception, cognition and neuroscience laboratory at Northwestern.
